Filter by:Recent small subcortical infarction (RSSI) is defined as a small deep infarction in the territory of a perforating artery with maximum axial diameters (MAD) of less than 20 mm. Although RSSI is generally considered to be of a relatively favorable prognosis, about 13.5% to 43% of RSSI patients experience early neurological deterioration (END) in the acute phase, which often bring adverse effects on long-term outcomes. Although a number of risk factors for END have been identified previously, however, the risk factors of END and the underlying etiological mechanism are still ambiguous, and also the relevant intervention measures lack sufficient evidences, which is a thorny problem that clinicians have to face. In this multicenter, large-sample prospective registry study, we ought to investigate the natural course of END in patients with RSSI. Exploring the risk factors and potential mechanism of its occurrence and development, and trying to establish a comprehensive predictive model for END that integrates multi-dimensional information including clinical symptom, demographic data, biochemical biomarker and image data, and so as to provide a valuable tool for clinical evaluation and early management. Simultaneously, our study will provide information for the design of therapeutic randomized controlled trials in the future.
This is a prospective, multicenter, cohort study aiming to compare the safety and efficacy of Embotrap stent retriever to other stent retrievers without inner channel for acute middle cerebral artery occlusion (MCAO). All enrolled patients will be followed up at 90 days after randomization.
The MATISSE (Molecular Analysis of Thrombus for Ischemic Stroke prognosis and Etiology) project evaluates the hypothesis that the molecular composition of cerebral thrombus in metabolites, lipids, and proteins conditions the clinical prognosis at 3 months of the infarction and informs on its etiological subtype
Most ischemic stroke patients are in recovery phase, often accompanied by motor impairment, but they lack effective treatment. The appearance of nerve growth factor (NGF) promotes the development of neuroprotective therapy, but it has little effect on stroke because of the blood-brain barrier (BBB). Electroacupuncture (EA) has been used for stroke, while there is no significant clinical effect for recovery phrase. Consequently, we will conduct a multicentre, randomised, controlled, assessor-blinded clinical trial to assess the effectiveness and safety of EA combined with NGF treatment on ischemic stroke recovery.
This study is a multicenter, prospective, cohort study to observe the clinical efficacy and safety of edaravone dextrol in patients with acute ischemic stroke in a real-world setting.
Excessive accumulation or abnormal distribution of adipose tissue is a recognized risk factor for ischemic stroke. However, the impact of overweight or obesity on clinical outcomes of ischemic stroke is uncertain. The proposition of obesity paradox in stroke patients makes secondary prevention ambiguous for patients with ischemic stroke and overweight or obesity. Body mass index (BMI) or abdominal visceral fat area was used to measure obesity in previous studies. Epicardial adipose tissue (EAT) is a unique visceral fat, which has higher expression of proinflammatory genes than subcutaneous fat and abdominal visceral fat. And inflammation is closely related to the prognosis of ischemic stroke. In this study, the investigators assume EAT volume or attenuation evaluated by chest computed tomography (CT) scan might affect the prognosis of patients with acute ischemic stroke (AIS). Patients with the first acute ischemic stroke will be stratified into tertile groups based on EAT volume or attenuation. The primary endpoint measure is the proportion of patients with a favorable recovery of nerve function deficiency assessed by Modified Rankin Scale （mRS≤2） at 90 days after the onset of symptoms. Secondary endpoints include the following: the percentage of functional recovery measured by the Barthel Index (BI) at day 90 after stroke onset, the propotion of clinical improvement (with an improvement of ≥ 4 points on the National Institute of Health Stroke Scale score or the resolution of the neurologic deficit) or neurological deterioration (with a decline by ≥ 4 points in the total National Institute of Health Stroke Scale score) at day 7 after stroke onset, incidence of hemorrhagic transformation and mortality within 7 days of symptom onset.
Can Semaglutide help reduce the damage caused by a stroke? ASSET trial is a national, multicenter, clinical trial, investigating the safety and efficacy of Semaglutide in non-diabetic patients with acute ischemic stroke. Stroke is a worldwide leading cause of long-term disability and death. In the most common type of stroke (ischemic stroke), a blood clot obstructs an artery in the brain, and thereby prevents oxygenated blood from reaching an area of the brain. Brain cells are particularly vulnerable to the lack of oxygen. In the areas most severely affected by a stroke, brain cells die after 5 minutes. As more time pass, the affected area expands, and more brain cells perish. Today, efficient treatments aiming at reestablishing the flow of blood by either breaking down the blood clot (thrombolysis) or removing the clot (thrombektomi) are used. However, a significant amount of patients undergoing succesful treamtent, still suffer permanent disability following an ischemic stroke. Semaglutide mimics a naturally occurring hormone (glucagon-like peptide-1) and is currently used to treat diabetes and obesity. However, semaglutide has also been shown to possess neuroprotective abilities in recent animal studies, where it reduced the damage caused by ischemic stroke in rats. This study sets out to investigate if it's possible to utilize Semaglutide, to increase the resilience of brain cells in patients with an acute ischemic stroke, with the aim of bettering their outcome. The participants consist of non-diabetic patients with acute ischemic stroke, who will be randomized to: - Treatment with subcutaneous Semaglutide, or - No additional treatment (control group) Both groups will be treated according to the standard national guidelies for acute ischemic stroke. The two groups will then be compared to see, if patients in the group treated with Semaglutide are less impacted by their stroke.
The molecular characteristics of ischemic stroke with phlegm-heat syndrome and candidate biomarkers were identified based on multi-omics data. The main purpose of this study is to validate the molecular characteristics and biomarkers of phlegm-heat syndrome in ischemic stroke, and to demonstrate the association of biomarkers with clinical outcomes.
To observe the safety and efficacy of intensive drug therapy for ischemic stroke patients.Patients with acute stroke caused by intracranial arterial stenosis (stenosis rate ≥70%) were enrolled and accept dual antiplatelet therapy (DAPT) (aspirin 100 mg/d and clopidogrel 75 mg/d for 90 days, followed by aspirin 100 mg/d for long term) under the guidance of platelet function analysis (Verifynow) combined with the intensive statin therapy (40 mg/d for 14 days, followed by 20 mg/d for long term).
